Place the chicken and shrimp in a food processor and process until finely chopped. Add the egg, shallots, garlic, cilantro, fish sauce, pepper and salt and pulse for a few seconds to mix well. Transfer to a large bowl.

Spread the mixture evenly over the slices of bread, right to the edges. Sprinkle the sesame seeds over a plate and press the spread side of each slice of bread into them to coat evenly.

Using a sharp knife, cut the bread into squares, making 4 toast per slice.

Heat up enough oil in a pan until hot. Pan fry the bread for 2-3 mins under medium heat on each side, or until golden brown, turning them over once.

Drain the toasts well on paper towels, transfer to a serving plate and serve immediately.

Note
Place the bread overnight in a fridge, it will make it easier to spread the mixture onto it. If making for a big party, these toasts can be made in advance. Cover and let chill in refrigerator for up to 3 days or place them in a sealed container in a plastic bag and freeze for up to 1 month. Thaw overnight in the referigerator and then pop into a hot oven for 5 mins to reheat thoroughly.
